that looks like a really poor, second-rate commercial website, not a proper educational resource. "Famous Castles in the World" is barely proper English--if you insist on "the World" in your appellation, I suggest "The World's Most Famous Castles." Or something.

"The World's Most Famous Castles." sounds fine. The problem is with the " ' " in World's; some search machines don't work correct with that spelling. But, may be you could find another option. --Joaquín Martínez 17:48, 19 February 2010 (EST)
